Driver-Based Attacks: Past and Present
"People that write Ring 0 code and write it badly are a danger to society." - Mickey Shkatov There is no security boundary between an administrator and the Windows kernel, according to the Microsoft Security Servicing Criteria for Windows. In our analysis of CVE-2021-21551, a write-what-where...
CVE-2021-26334
The AMDPowerProfiler.sys driver of AMD μProf tool may allow lower privileged users to access MSRs in kernel which may lead to privilege escalation and ring-0 code execution by the lower privileged user...
CVE-2021-26334
CVE-2021-26334 affects AMD μProf Tool via the AMDPowerProfiler.sys driver. The root cause is improper access control that could let a low-privilege user access MSRs in the kernel, enabling privilege escalation and potential ring-0 code execution. Affected product: AMD μProf (AMDuProf). Exploitati...
CVE-2021-26334 AMD Chipset Driver Information Disclosure Vulnerability

CVE-2021-31728
Incorrect access control in zam64.sys, zam32.sys in MalwareFox AntiMalware 2.74.0.150 allows a non-privileged process to open a handle to .\ZemanaAntiMalware, register itself with the driver by sending IOCTL 0x80002010, allocate executable memory using a flaw in IOCTL 0x80002040, install a hook...
Memory corruption
The UX360CA BIOS through 303 on ASUS laptops allow an attacker with the ring 0 privilege to overwrite nearly arbitrary physical memory locations, including SMRAM, and execute arbitrary code in the SMM issue 3 of 3...
CVE-2020-28921
An issue was discovered in Devid Espenschied PC Analyser through 4.10. The PCADRVX64.SYS kernel driver exposes IOCTL functionality that allows low-privilege users to read and write to arbitrary Model Specific Registers MSRs. This could lead to arbitrary Ring-0 code execution and escalation of...
Remote code execution
An issue was discovered in Devid Espenschied PC Analyser through 4.10. The PCADRVX64.SYS kernel driver exposes IOCTL functionality that allows low-privilege users to read and write arbitrary physical memory. This could lead to arbitrary Ring-0 code execution and escalation of privileges...
CVE-2020-15481
An issue was discovered in PassMark BurnInTest v9.1 Build 1008, OSForensics v7.1 Build 1012, and PerformanceTest v10.0 Build 1008. The kernel driver exposes IOCTL functionality that allows low-privilege users to map arbitrary physical memory into the address space of the calling process. This cou...
CVE-2020-15479
An issue was discovered in PassMark BurnInTest through 9.1, OSForensics through 7.1, and PerformanceTest through 10. The driver's IOCTL request handler attempts to copy the input buffer onto the stack without checking its size and can cause a buffer overflow. This could lead to arbitrary Ring-0...

CVE-2019-7246
An issue was discovered in atillk64.sys in AMD ATI Diagnostics Hardware Abstraction Sys/Overclocking Utility 5.11.9.0. The vulnerable driver exposes a wrmsr instruction and does not properly filter the Model Specific Register MSR. Allowing arbitrary MSR writes can lead to Ring-0 code execution an...
CVE-2019-7247
An issue was discovered in AODDriver2.sys in AMD OverDrive. The vulnerable driver exposes a wrmsr instruction via IOCTL 0x81112ee0 and does not properly filter the Model Specific Register MSR. Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges...
Privilege escalation
An issue was discovered in AODDriver2.sys in AMD OverDrive. The vulnerable driver exposes a wrmsr instruction via IOCTL 0x81112ee0 and does not properly filter the Model Specific Register MSR. Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges...
CVE-2019-7246
The CVE-2019-7246 entry concerns the AMD ATI Diagnostics Hardware Abstraction Sys/Overclocking Utility driver atillk64.sys (version 5.11.9.0). The vulnerability arises from improper filtering of Model Specific Registers (MSR) and exposure of a wrmsr instruction, allowing arbitrary MSR writes that...
